Heybridge Swifts FC – 200 Lux Match Floodlighting Proposed Floodlighting Installation 06th October 2016 Optivision is a double asymmetric downlighting luminaire that combines compact dimensions with very high efficiency. Available with narrow, medium and wide beams for flexibility in application, it provides excellent control of spill light and limitation of glare and upward leakage of light. Optivision accommodate metal-halide lamps for good colour rendering. Excellent spill-light control, limitation of glare and upward leakage of light is secured by asymmetric optics that achieve peak intensity at 62º and a sharp cut-off of light at 80º. The MHN-FC lamps guarantee pleasant and natural colour rendering and comfortable atmosphere. Louvres have been installed to all 16 Luminaires to ensure spillage is an absolute minimum. This lighting design has been created in accordance with guidance notes recommended by the ILP (Institute of Lighting Professionals) for the reduction of obtrusive light, which advises that within Zone E2 (Low district brightness areas) you should achieve the following: Source intensity (Glare) should not be above 7500cd. Vertical Illuminance should not be above 5 Lux on windows Upward Light Ratio should not be above 2.5% Within the lighting design, “Observer points” have been put in to demonstrate the luminaire intensity (Glare) at three points on the adjacent property. The calculations are on page 4 of the spillage calculations and have been calculated at: Ob1 – Result = 821cd Ob2 – Result = 618cd Ob3 - Result = 284cd The results are below the guidance notes recommendations of 7500cd ---------------------------------------------------------------------------- Within the lighting design, Vertical calculations have been put in to demonstrate the vertical illuminance on the windows (Light Intrusion) of two locations on the adjacent property. The maximum readings are on page 4 of the Spillage calculations, and have been calculated at: V – Adjacent Property 1 – Result = 0.42 Lux V – Adjacent Property 2 – Result = 0.10 Lux The results are below the guidance notes recommendations of 5 Lux ----------------------------------------------------------------------------- The Upward Light Ratio (ULR) is 0.00 - Page 4 Spillage Calculations This is below the guidance notes recommendation of below 2.5% ----------------------------------------------------------------------------- All results have been calculated at a Maintenance Factor of 1, this means that no allowance has been made for lamp depreciation. The results have been calculated with the lamps at their greatest luminance.

NIGHT TIME PHOTOS OF PREVIOUSLY INSTALLED FLOODLIGHTING The image below shows a night-time photograph of a similar floodlighting scheme installed on an all weather hockey pitch, elsewhere in the country. This illustrates the ‘cut-off’ of light from the proposed floodlights. It should be noted the direct light is in a downward directions.

The photograph below of an all weather hockey pitch has been taken from a high location and shows the extent of the lighting footprint. This indicates the dramatic ‘cut-off’ of light a short distance from the pitch using the proposed floodlights on 15m high columns.

Guidance Notes for the Reduction of Obtrusive Light GN01:2011

GUIDANCE NOTES FOR THE

REDUCTION OF OBTRUSIVE LIGHT

“Think before you light - The right amount of light, where wanted, when

wanted.”

Man's invention of artificial light has done much to safeguard and enhance our night-time

environment but, if not properly controlled, obtrusive light (sometimes referred to as

light pollution) can present serious physiological and ecological problems.

Obtrusive Light, whether it keeps you awake through a bedroom window or impedes your

view of the night sky, is a form of pollution, which may also be a nuisance in law and which

can be substantially reduced without detriment to the lighting task.

Sky glow, the brightening of the night sky, Glare the uncomfortable brightness of a light

source when viewed against a darker background, and Light Intrusion (“Trespass”), the

spilling of light beyond the boundary of the property or area being lit, are all forms of obtrusive light which may cause nuisance to others and waste money and energy. Think

before you light. Is it necessary? What effect will it have on others? Will it cause a

nuisance? How can you minimise the problem?

Figure 1 – Types of obtrusive light

Do not "over" light. This is a major cause of obtrusive light and is a waste of energy. There

are published standards for most lighting tasks, adherence to which will help minimise

upward reflected light. Organisations from which full details of these standards can be obtained are given on the last page of this leaflet.


2

Dim or switch off lights when the task is finished. Generally a lower level of lighting will

suffice to enhance the night time scene than that required for safety and security.

“Good Design equals Good Lighting”

Any lighting scheme will consist of three basic elements: a light source, a luminaire and a method of installation.

Light sources (Lamps)

Remember that the light source output in LUMENS is not the same as the wattage and that it is the former that is important in combating the problems of obtrusive light.

Most nightime visual tasks are only dependant on light radiated within the visual spectrum.

It is therefore NOT necessary for light sources to emit either ultra-violet or infra-red

radiation unless specifically designed to do so. It is also understood that light from the

shorter wavelengths of the spectrum has important effects on both flora and fauna that

should be considered.

Research indicates that light from the blue end of the spectrum has important non-visual

effects on the health of the human body, in particular in our sleep/wake patterns. It is

therefore important to appreciate that while in obtrusive light terms the use of blue light

should be minimised, there are many night-time tasks such as driving and sports where to

be fully awake is an important aid to safety.

Luminaires

Care should always be taken when selecting luminaires to ensure that appropriate products

are chosen and that their location will reduce spill light and glare to a minimum.

Use specifically designed lighting equipment that minimises the upward spread of light near

to and above the horizontal. The most sensitive/critical zones for minimising sky glow are

those between 90o and 100o as shown in Figure 2 and referred to as the lower, upward

light output zone (UL).

Figure 2 – Critical luminaire angles

For minimising sky glow


3

For most sports and area lighting installations the use of luminaires with double-

asymmetric beams designed so that the front glazing is kept at or near parallel to the

surface being lit should, if correctly aimed, ensures minimum obtrusive light.

Appendices 1 and 2 to these notes gives more details of how to choose and if necessary

modify luminaires.

Installation

In most cases it will be beneficial to use as high a mounting height as possible, giving due

regard to the daytime appearance of the installation. The requirements to control glare for

the safety of road users are given in Table 3.

Keep glare to a minimum by ensuring that the main beam angle of all lights directed

towards any potential observer is not more than 70o. Higher mounting heights allow lower

main beam angles, which can assist in reducing glare. In areas with low ambient lighting

levels, glare can be very obtrusive and extra care should be taken when positioning and

aiming lighting equipment. With regard to domestic security lighting the ILP produces an

information leaflet GN02:2009 that is freely available from its website.

Figure 3 – Luminare aiming angles

Poor Okay Good

When lighting vertical structures such as advertising signs, direct light downwards wherever possible. If there is no alternative to up-lighting, as with much decorative lighting

of buildings, then the use of shields, baffles and louvres will help reduce spill light around

and over the structure to a minimum.

For road and amenity lighting installations, (see also design standards listed on Page 5)

light near to and above the horizontal should normally be minimised to reduce glare and sky glow (Note ULR’s in Table 2). In rural areas the use of full horizontal cut off luminaires

installed at 0o uplift will, in addition to reducing sky glow, also help to minimise visual

intrusion within the open landscape. However in some urban locations, luminaires fitted

with a more decorative bowl and good optical control of light should be acceptable and may

be more appropriate.

Poor Good Good

Since 2006 “Artificial Light” has been added to the list of possible Statutory Nuisances in

England, Wales and Scotland. The monitoring of such nuisances will be the responsibility

of Environmental Health Officers (EHOs) for which separate guidance is being produced.

With regard to the planning aspect, many Local Planning Authorities (LPAs) have already

produced, or are producing, policies that within the planning system will become part of

their local development framework. For new developments there is an opportunity for LPAs

to impose planning conditions related to external lighting, including curfew hours.

The Scottish Executive has published a design methodology document (March 2007) entitled “Controlling Light Pollution and Reducing Energy Consumption” to further assist in

mitigating obtrusive light elements at the design stage.

ENVIRONMENTAL ZONES

It is recommended that Local Planning Authorities specify the following environmental

zones for exterior lighting control within their Development Plans.

Where an area to be lit lies on the boundary of two zones the obtrusive light limitation

values used should be those applicable to the most rigorous zone.

NB: Zone E0 must always be surrounded by an E1 Zone.

DESIGN GUIDANCE

The following limitations may be supplemented or replaced by a LPA’s own planning

guidance for exterior lighting installations. As lighting design is not as simple as it may

seem, you are advised to consult and/or work with a professional lighting designer before

installing any exterior lighting.

ULR = Upward Light Ratio of the Installation is the maximum permitted

percentage of luminaire flux that goes directly into the sky.

Ev = Vertical Illuminance in Lux - measured flat on the glazing at the centre of

the window.

I = Light Intensity in Candelas (cd)

L = Luminance in Candelas per Square Metre (cd/m2)

Curfew = the time after which stricter requirements (for the control of

obtrusive light) will apply; often a condition of use of lighting applied by the local planning authority. If not otherwise stated - 23.00hrs is suggested.

* = Permitted only from Public road lighting installations

(1) Upward Light Ratio – Some lighting schemes will require the deliberate and careful use of upward light, e.g. ground recessed luminaires, ground mounted floodlights,

festive lighting, to which these limits cannot apply. However, care should always be

taken to minimise any upward waste light by the proper application of suitably

directional luminaires and light controlling attachments.


6

(2) Light Intrusion (into Windows) – These values are suggested maxima and need

to take account of existing light intrusion at the point of measurement. In the case of

road lighting on public highways where building facades are adjacent to the lit

highway, these levels may not be obtainable. In such cases where a specific

complaint has been received, the Highway Authority should endeavour to reduce the

light intrusion into the window down to the post curfew value by fitting a shield,

replacing the luminaire, or by varying the lighting level.

(3) Luminaire Intensity – This applies to each luminaire in the potentially obtrusive

direction, outside of the area being lit. The figures given are for general guidance

only and for some sports lighting applications with limited mounting heights, may be

difficult to achieve.

(4) Building Luminance – This should be limited to avoid over lighting, and related to

the general district brightness. In this reference building luminance is applicable to

buildings directly illuminated as a night-time feature as against the illumination of a

building caused by spill light from adjacent luminaires or luminaires fixed to the

building but used to light an adjacent area.

TI = Threshold Increment is a measure of the loss of visibility caused by the

disability glare from the obtrusive light installation

Lv = Veiling Luminance is a measure of the adaptation luminance caused by the

disability glare from the obtrusive light installation
